About the Ancient 14


Jared Diamond, in Guns, Germs, and Steel, describes 14 animals domesticated in ancient times. These species are known collectively as the Ancient 14. What are these species? Watch our class' VoiceThread about the oldest large mammals domesticated by humans.

Why Domestication Fails


6 reasons are given by Jared Diamond (pages 168-173).
  1. Diet
  2. Growth rate
  3. Problems of captive breeding
  4. Nasty disposition
  5. Tendency to panic
  6. Social structure
The results of our analysis of a number of domestication failures is in this Google Spreadsheet: Anna Karenina Principle. (completed in class on November 1)

Zebras and Unhappy Marriages


Why were only 14 large terrestrial mammals domesticated? Some 148 species match the initial requirements. Why weren't animals like zebras, bighorn sheep, and the buffalo brought under human control?
